::-..-Be it known that I, JOSEPH Bg K'monu, a

citizen of the United States, residing at RVash-ington, in the District of Columbia,

have invented certain new and usefulImprovements in Vehicle Springs, of which the following is a specification.

This inventiion relates to vehicle springs, and especially that'type adapted for autnmobiles and-like vehicles, 'and consists "of I an improvement upon and development of the 1 springs disclosedby my Patent No.

com fort. era]. rule, the annoying vibrations, 'osc1llaeral organization of elements operating in the same manner and having the same effi- 'cient resiliencyas the springs 'disclosed'by my aforesaid application.

COne of the prime considerations-of the public in the purchase of passenger automobiles for pleasure or otherwise is riding It iswell knownthat as a gentions and joltin-gs of automobiles when moving over n'nevcn road surfaces vary inversely with the weightof the vebi'ele, or with its equivalent, the pressure exerted on the springs by the vehicle body. In the 'final analysis, is clear that the riding qualities of a machine depends largely upon the pssure exerted on the springsl by the vehicle body, asa heavy car, as" well as a lifllst one would ride roughly withoutsprings, In view of this obvious condition, heavy cars'are often purchased at. a much i'eatei" expense rei-itively to lighter cars,

-in order that this riding comfort may be obtained.

The present improvement contemplates and-provides a very simple and inexpensive airing orgnni ation by which the pressure H exerted on a main bra-ring spring unit -cooperating with the "vehicle body may be mechanically increas d to any desired extent without con-repmdingly increasing the wei ht of the vehicle body, t hus ivin a b I h i" machine or vehicle the easy ri'd'ingvqualit-ies so much desired. without. the expense 111'- volved in brildina a heavier machine. By

7 the adoption of the improved spring organization, heavy machines, also, may be given those riding qualities hat would be attained y a still hea ier machine construction.

The preferred form of and the simple details in the-spring organization embodying the features of the improvement andby which the results sought maybe obtained,

are illustrated in the accompanying drawing,

wherein r 1,3511305, dated June 1, 1920. The present essential to thesuccessfuloperation or funcai mprovement embodies a structure and eentioning of the'improved spring organization, andvarioustypes of vehicle bodies,

frames, and the usualor requisite accessories may be used. The improved organization is interposed between the vehicle body or its frame, which-may be comprised in the body equipment in contradistinction to the running gear, and the axle, and consists essentially of a. spring'unit ,9 of any preferred or adaptable form and'a rigidintermediate support 10 of any suitable and requisite length and width and of any preferred construction. The spring unit 9 may be movably secured atone extremity to any 'part of the vehicle body,- or,- 'as shown, to the frame by link means 11', its opposite extremity being fixed to the intermediate support 10 as at 10. Theixiter mediate support 10 is movablv secured at its forward end 12 to the vehicle-body or' extremity of the said support by link means 16. In the form of the imprgvement-gshown by Fig. 2 the rear extremity of the sup-. port 10 is directly connected to the axle 7 by clip means 17, the spring unit 14 being omitted. The forward end'of the spring unit 9 in either form of the improvement, may be attached to the support 10 at any point found best adapted to meetand practically operate with vehicle bodies and frame structures varying in weight. The spring which vibrates or a connecting features in both said support. This increased pressure, so far as spring resiliency and operation under normal stress are concerned, is equivalent to increasing b a'likeamount the actual weight of the vehic e body. For example, if, on a particular machine or vehicle, the point of attachment of the spring unit 9 to the inter;

' .mediate support 10 be so placed ast-oincrease the pressure on said unit by-25 per centum over, that of the pressure on the spring unit now commonly used, then an 800 pound pressure or body weight on the spring unit now commonly used would/result in the same operation asa 600 pound pressure would on the spring unit 9, as both spring units under these conditions would be subject to the same relatively. controlled pressure. Thus a vehicle or machine exerting a 600 pound pressure or body weight on the spring unit 9 ;would run as smoothly as a vehicle or, machine exerting an 800 pound pressure on its spring unit. By the resent improved structure, the weight, so a r as spring response is concerned, can be artifically increased to any desired proportion, depending upon the point on the intermediate support at which the spring unit- 9 is attached, whether nearer the forward or rear end of the support. In other words a light machine on a spring structure or unit similar to the unit 9 can be made to ride as smoothly as a heavier machine over the ordinary spring structure now in use. It will therefore be understood that the spring unit 9 may have its forward end shifted over and fixed to the support 107-at different points as maybe found desirable and necessary to meet the variation of Weight stress of vehicle bodies imposed on the improved spring organization.

The organization shown by Fig. 1 has an additional advantage. The rear end of the lower spring unit 14 will communicate its vertical oscillations, caused byalternate comprcssion and rebound, to'the spring unit 9 to a much less pronounced extent than is the case in the commonly used spring structure, Thisresult is due in a large measure to the movably mounted support 10 to which both spring units 9 and 14 are attached. As in my previous construction embodied in my patent hereinbefore mentioned, the fund nxleasshe'wn by '2, is the same, said-I tunction' being to sustain thefspring units or unit during rebound and sway neutralizing and suppression operations, this function being auxiliated by the movable attachment of the support and the movable connection ao'f the spring units or unit thereto. This jfsupport also eases the movements, of the spring ,units or unit in assuming abnormal positions and return to normal positions.

The present improvement inf'both forms shown and described, absorbs or neutralizes u ward thrusts, rebounds or sways and mini izies resultant movements of the vehicle body, in a practical and efficient manner. The appreciable effect of the upward move mentsofjhe axle be very small and consequently the running motion of the vehicle will be exceedingly smooth and quiet.

The s ring units hereinbefore described,

are not. imited to any particular structure and may be composed of any number of parts or members, the term unit being intended to comprise any spring means that may be employed to successfully perform the function and obtain the result sought. Furthermore, the intermediate su be of any preferred structure an material, it only being n ry to provide a support means mounted have a vibrating or oscil- ,lating movement, and to provide a leverage means for mechanically increasing the pres sure on a spring unit.

What is laimed as new is In a spiing organization of the class specified, the combination with. a 'vehicle body and running gear including an axle, of an oscillating rigid. support mcvably at tached at its front eirtremlty the vehicle body'and extending over the axle in a normal horizontal plane and connected to said axle, and a spring unit movably attaehed'at its upper end to port may to a portion of rearwardly the rear, portionof the vehicle body andinclined forwardly and downwary under the rear portion of said body and connected at its lower end to an intermediate portion of the said su port, the lower end of said spring unit iieing applied and connected to the support at such distance between the ends JOSEPH B.
